    power: reset: Add Intel PIIX4 poweroff driver · 29676833
    Paul Burton authored
    Add a driver which allows powering off the system via an Intel PIIX4
    southbridge, by entering the PIIX4 SOff state. This is useful on the
    MIPS Malta development board, where it will power down the FPGA based
    board until its ON/NMI button is pressed, or the QEMU implementation of
    the MIPS Malta board where it will cause QEMU to exit.
